i believe the first is the one on black joy 12" entitled stop them jah

i think the second one is taken from one of those 10" re that came out and is called 'warrior'

the last one i believe its called 'dem a say rasta' which came also one one of those 10" attack

i have to say that i didnt check, just my memory but i think you can find them all on youtube

theres even another cut by johnny same lyrics only a steppers version... never seen it on any format but ive heard it (could be dubplate tho)it rides the same riddim as george nooks - children of israel (not the released one)
